oracle 11g关机中止后长启动

我的意思是关机数据库有shutdown immediate，但是20分钟后没有完成。然后我用shutdown abort关闭它。当我开始时，需要3-4小时将mount状态更改为open。下面是alter.log：oracle 11g关机中止后长启动

这意味着一个巨大的交易正在发生在您立即关闭的时间，通过关闭中止，您只是在开始时推迟回滚解释了为什么启动需要这么长时间。 –

关闭中止数据库在打开数据库之前将执行崩溃恢复。时间相关 1.体积块需要恢复，因为oracle会前滚重做恢复损坏的块。磁盘

对于第一个二，性能还可以通过设置FAST_START_MTTR_TARGET参数减少，或者你可以设置重做日志文件的大小超过系统的经验，正确的值。对于第二个你应该使用性能更好的磁盘。
